driven by means of a belt 2 that i'n turn is driven b va pulley .24. first on the axle .5 of

the engine, which fan. however, may of.

course be driven by anv other suitable means. Thefan is provided with the usual casin .26. The blast of air created by the fan .22 is driven into the space 13 through a hollow connection 27 as best shown in Fig. 5, the fan being supported on a plate 28, formed with or secured to such hollow connection. and said conncc tionbeing bolted orothcrwise'firlnly secured to the jacket 12, which jacket is provided with an opening through, its side wall communicating witb the pass-a e iii the connection 27, as clearly shown in ig. 5. V It has been found highly desirable to force into the space 13 with the air a small amount of-liquid material as thereby the niorera id coolingof the cylinder is facilitated, ant if such small amount of liquidis" introduced into the device that creates the air-blast, so as to be discharged therefrom with the air, or if such liquid be introduced into the current blast of air some little distance from the gaunt at which such current or blast enters e space 13, such liquid-will at the time it enters said space 13 be convcrted'int-o a vapor. In Figs. 1, 2, 4, and 5 I have illustrated mechanism for introducin this liquid dineatly into the air-blast-prot ucin means-to wit the fan before referred to. lieferring to such means, 29 indicates a liquid-reservoir,

which in the form of construction shown is formedwith the hollow connection 27 and is curved to conform to the curvatureof the c linderj 10. such curvature being shown in i .4. cabon at one end with the lower end of the liquid-reservoir ."J and adapted to discharge liquidtherefrom into the casing 26 of the fan, sothat it will be forciblv ex )elled with the ,air-blast-caused by such inn t trough the hollow conn ction 27 into the space 13 between the cylint er 1U undjacket 12, such liquid, as before stated. being converted into a vapor by the time it reaches said space 13. Reaching such space the cooling agent-that is, the

air and the .vapor--is forced around said cylmder and by the means heretofore described into and through the hollow base 11 and up through numerous small openings I5 in the horizontal portion of the jacket 12, passing from thence up and against the has on the upper portion f the cvhnder and between 30 indicates a pipe having connnuniand against the radiating and heated projections 1-1. The mam discharge for the cooling agent is through a passage 15*, extendingthrough the wall of the surrounding jacket, such lllNlltIX'gQ-PiISStIgt being of eonsiderablv less diameter than the passage through which the cooling agent enters the s nice 13, and by reason of such difference in tl diameters of these two passages the coolin agent will be forced to fill-the space 13 and a portion of it will also be forced into ahd through the hollow base and another portionup through the small openings lo.

The construction described enables a blast of air to be dischargedwith greatforce around, against, and under a heated cylinder and to cool the same rapidl and ellectiv'ely, and by the introduction of iquid in small quantities with the blast of air and the conversion of such liquid into va or b the time it reaches the space between t 1e cylinder and the jacket the coolin operation is found to be very much'facihtatcd. As shown, the pipe 30 is provided with a suitable valve 31, by which the 'uant-ity of liquid fromthe reservoir 29 may 9 rc ulated as desired.

-That 'wbich I claim as rnv invention, and desire to secure by Letters Patent is l. The conibination with a c linder provided on its up er portion with longitudinally-arranged s, and a jacket surroundingthe lower portion of said cylinder, said jacket having an upper end wall portion in which is a series of openin registering with the spaces between said b ns, of means for admitting a cooling a cut to the space between said cylinder and jacket, substantially as specified. i

i 2. The combination with a c 'linder provided units up' er port-ion wit longitudinally-arranged ns, .and a.jacket surrounding the lower portion of said cylinder, said jackethaving an upper end wall port-ion in which is a series of openinfilregistering with the spaoes'between said 5, of means for forcing acooling agent into the space be- .tweenzsaid cylinder and jacket and out of said openings to direct it between said fins and against the surface of the upper portion of the cylinder, substantially as s ieclfied.

3. The combination with a cvl inder provided on its up er portion wit longitudinallyarranged s, and a jacket surrounding the lower portion ofsaid cylinder, said jacket having an upper end wall portion in which is a series of openin s registering with thespaces between said us, of means for producing a vappr, and means for forcing said va or nto t e space between said cyhnder an jacket andout of said openings so that it will be directed between said fins and a ainst the surface of the upper portion of t e cvlinder, substantially as S )ecified.

4. The combination with a cy inder and a jacket surrounding the lower portion therespace between of, said jacket having an apertured wall at its lkpper end through which a cooling agent is a apted to be directed against the upper portion of the cylinder, of a hollow base for said cylinder, the interior of said base coniin'unicating with the space between the cylof, said jacket having an apertured Wali at its 11 per end through which a cooling agent is a apted to be directed against the upper ,portion of the cylinder, ofa hollow. base for sai cylinder, the centralportion of the top of t e base fitting within the cylinder and the interior. of the base communicatin with the the cylinder and t e jacket,

' and means for forcing a cooling agent through said base and the spacebet'ween the c finder and jacket, substantially as speci- -fi '6. The cornbination with a cylinder and a jacket surrounding the lower portion thereof, said jacket having an apertured wall at its .u per'end through which a cooling agent is a apted to be directed against the upper portion of the cylinder, of ahollow base for said cylinder, the interior of said base cornrnun'icating with the space between the cylinder and the jacket, and means for forcing a by said fan, substantial cooljng agent througlfsaiti base and the space between the cylinder and jacket, said cooling agent having an exit inaddition to the openings in the u per wall of the jacket, such additional exit lacing of less size than the opening through which the cooling agent enters the-jacket, substantially as s eoified.

7. The combination with a cylin or provided on its upper portion with a series of fins, and a 'acket surrounding the lower portion of sai cylinder, said jacket having an upper end we 1 ortion in which is a series of openings, of a ail-blower, means of drivin said fan-blower, a liquid-reservoir, and means for conducting liquid from said reser voir into the path of the air-current created by said fan substantially as specified.
